if you've ever had trouble creating cohesive color palette, using gamut masks might help. A gamut mask is a tool developed by artist James Gurney that helps you to create amazing color harmonies by limiting your color choices. To use a gamut mask all you have to do is take a color wheel and draw a shape over it. This technique can be used for both physical and digital media.
By forcing your self to use a limited range of colors you get more streamlined color palettes that can change the mood and feel of your pieces.The beauty of gamut masks is that you can make any shape you want witch can lead to amazing color palettes you wouldn't normally think of
Using a gamut mask for physical media is fairly strigat forward but for digital media it can be a little complicated. The only drawing program that supports gamut masks out of the box is Krita, But there are tools you can use to make gamut masks in any program.
Artist Aaron Rutten has created a universal gamut masking program that can be used in over 8 different drawing programs.
